Yeah, of course a superposition is possible. You're asking the Schroedinger's Cat question.

Your own words

can be translated as if you were preparing an experimental collision between the two systems. Right? Then, this means that the initial condition you consider is a superposition of the mixed states for the composite system. At the start the superposition is separable. But with evolution of this system all possible outcome will enter into the state vector of the system. However, if the collision is successful, some component -annihilation- may dominate the picture: annihilation is nearly certain. Conversely, if the collision is a little bit too much off-target the system will almost surely escape annihilation. This picture may be complemented by other possible outcomes ...... and you attempt to combine with antimatter deuterons ...

Thank you albatros. It is the second part of your above statement that I now try to understand from both the physics and more importantly the mathematics. Are you aware of any mathematical argument that would allow the collision to be successful, and for matter [PNP] + antimatter [N^P^] to form superposed union, and escape annihilation ? Perhaps some form of one of the Dirac equations ? If not, is there a mathematical argument that proves such collision as stated above impossible ? On first glance, one may think that collision of matter [PNP] + antimatter [N^P^], would just yield a [P], with the rest involved in annihilation and lots of gamma ray energy released. But, this would not happen if the two can form a superposition, this is what I try to understand mathematically, how such a superposition may be possible. Finally, has CERN or other experimental labs that work with antimatter ever tried this experiment ? It is really a very simple system to test, collision between matter helium-3 [PNP] with antimatter deuteron [N^P^], at different collision energies--does anyone know if this experiment has been conducted ?lalbatros said:...if the collision is successful, some component -annihilation- may dominate the picture: annihilation is nearly certain.

Thank you David. I am really interested if matter helium-3 [PNP] can form a stable superposition with antimatter anti--deuteron [N^P^], where I use ^ =antimatter. The positronium that you mention is very unstable, so only very weakly "bound".David said:Are you really interested in whether they can form a superposition or whether they can form a bound state? It's not really clear from your question why exactly you are asking and knowing that would help us give you the information you need.

I am interested because there is a cluster model by the late nuclear physicist Ronald Brightsen (MIT, 1950, worked under Dr. Charles Coryell at MIT on isotopes) that predicts that the above matter + antimatter superposition is possible--but he never published on the mathematical dynamics that would explain how the superposition would occur. He only mentioned that the outcome is two superposed states (1) what we call the proton [P], and (2) a hidden state with matter+antimatter {[NP][N^P^]}. I search for someone with the interest and time to take on the task of developing the required mathematics. I have posted the link to the model at many other threads, but here it is again: http://www.brightsenmodel.phoenixrising-web.net [Broken]
